The present inventioncombetweentheindividual panels, and the back prises an. elongated orsubstantially rectanboard whereby circuit connections to each gularshaped receptacle 1, provided with a panel maybe broken temporarily,while the hinged lid 2, at its open top side, and being providedfurther, with suitable means 3, whereby the cover or lid, may be lockedin closed position, when the operative parts contained within thereceptacle are in proper order.

Each end of the receptacle is provided with a plurality of bushings, l,of insulating material, and thru which the various conductors to themechanism within the receptacle, may extend. Also, suitable fuses 6, mayobviously be interposed in the circuit in accordance to these needs.

Secured vertically and at each end of the back wall of the receptacle,is a guide 7, eac of these guides being provided with a pair ofguideways. A back board 8 is mounted for vertical movabilitv within thereceptacle by having its ends disposed within the innermost guideways ofthe guides 7. This backboard is adapted to rest upon its lowerlongitudinal edge in the manner shown in Fig. 3, and is o1 a widthsufilcient to substantially abut the lid 2 at its upper edge to preventany vertical movement thereof.

Two spaced pairs 01' guioe plates 9 E), are secured in vertical positionon the back board, in the manner clearly shown in 1. Each of pair ofguide plates are disposed with their single guidewa s facing in oppositedi rection, so that the outermost guide plates of each pair will haveits guideway in opposed spaced relation to the guide '5, while theinnermost guide plates will have their guideways also in spaced opposedrelation.

A. slide panel 10 mounted vertically slidable between the guideways inthe manner shown in F i g. 1. An angle bar 11 is secured to the backboard below each panel to support the same, spacedly above the bottom ofthe receptacle.

As is perspectively shown in Fig. 10 of the drawing, an L-shaped member1 is secured below each panel 10 and to the back board. Upon thehorizontally disposed portion of each member 12, is a tl-shaped member13, secured at its bight portion. The bight portion of these lei-shapedmembers are provided with a laterally disposed lug 14 to which the mainfeed line is connected.

A bar 15 is horizontally disposed and connected to the back board 8above the upper end of each panel. This bar is prei craoly of aninsulating material, while one end th ereoif is pivotally securedbetween the free ends of an il -shaped support- 16, which is secured atits bight, to the back board above the space between the panels.

Each of these bars 15, is provided with. a pair of clamped bands 1717,to which the usual timing wires are connected. Each bar is furtherprovided with an additional clamped band 17, having connection with theusual load wire of the signal system.

Each panel is provided with a pair o plates 19-19, which project abovethe top edge of the panel and to which is secured a spring clip 20,adapted to contact with the bands 19 of the bar 15, to maintain acircuit to the conventional electromagnetic device A, from the timingmechanism, through the conductors 18.

[in additional upstanding plate 21 is likewise provided with a similarclip for con-- tact with the ban d 17, oi" the bar 15, for maintaining asurface connection of the usual load wire througl'i the conductor 22, tothe conventional circuit maker and breaker B The "feed side of thecircuit maker and breaker has connection to a depending conductor plate23, which engages between the upstanding spring legs of the lJ-shapedstationary contact 13.

In the operation of the conventional mechanism, designated by A and Brespectively the working parts are mounted in the manner disclosed inFig. 1, and during the operation of this type of mechanism, frequentlyrepairs or replacements are necessary. Heretofore in order to performthe same, it was necessary to disconnect the particular lamp circuitcontrol impaired.

By mounting the circuit controlling mechanism to each signal light, on aseparate panel, and supporting this panel removably on the removableback board, of this invention, when the pivotal bar 1:3 is swungoutwardly from the back board, so as to disconnect the clamped band fromthe clips carried by the back board, or panels, the panel with which thesaid moved bar is associated, may be lifted vertically from thereceptacle.

this panel may need repair, requiring considerable time, another panelcarrying the same mechanism may he slid within the guideways, foroperative disposition in lieu of the impaired panel. It will be seenthat when the panel needing repair is lifted Vertically, the conductorplate 23, breaks the con tact with the current feed contact 13, whereasthe timing connections have been primarily broken by the movement of thebar 15.

llllltllGIIilOIG, the receptacle is preferably filled to a level abovethe contact points oi the conventional circuit maker and breaker B, withoil, designated by numeral 24:. B this provision, the various movableparts of the mechanism will be thoroughly lubricated, thus requiringlittle attention, and alsoserving materially to lessen the noiseresulting from the operation thereof.

Having thus described my invention, what 1 claim as new is 1. Indemountable supporting means for multiple circuit controllers, whereineach circuit is controlled by an independent circuit making and breakingmechanism, a plurality oi demountable panels each supporting anindependent circuit actuating mechanism, switch means carried by thesaid panels for connecting the mechanisms thereon to the associatedconductors, means for securing said panels against displacement, saidmeans consisting of a base board upon which are arranged pairs of spacedguides in which the panels are slidable, and elements carried by saidbase board for fixing the positon of the said panels.

2. In demountable supporting means for multiple circuit controllers,wherein each circuit is controlled by an independent circuit making andbreaking mechanism, a plurality of demountable panels, each supportingan independent circuit actuating mechanism, a base board upon which thepanels are mounted, and switch means between said panels and the baseboard for connecting the independent circuit actuating mechanisms toconductors associated therewith.

3. In demountable supporting means for multiple circuit controllers,wherein each circuit is controlled by an independent circuit making andbreaking mechanism, a plurality of demountable panels, each supportingan independent circuit actuating mechanism, a base board upon which thepanels are mounted, and switch means between said panels and the baseboard for connecting the independent circuit actuating mechanisms toconductors associated therewith, said switch means including a bar ofconductive material pivotally connected at one end to the base boardadjacent each panel, and complementary contact means between the barsand the circuit actuating mechanism thereon.

In testimony whereof I affix my signature.
